Instarmac UltraCrete Mortar Buoy | Access Frame Installation Aid

Where to use

Mortar Buoy® promotes next generation access frame installation. The inflatable configuration allows for a flowable mortar installation creating a dam within seconds. The Mortar Buoy® dam prevents any mortar seeping into the access chamber providing a seamless finish to the chamber and trim back areas. This allows a single pour installation of Envirobed® CD534 Flowable/ Envirobed® CD534 Flowable Red, which encapsulates the flange of the access frame creating a solid bed and backfill in one.
